so according to the docu https://pingouin-stats.org/generated/pingouin.mixed_anova.html#pingouin.mixed_anova mixed_anova returns a DataFrame object including sphericity.
aov = mixed_anova(...)
display(aov)
this doesnt show the sphericity.
and things like:
aov.sphericity()
aov['Sphericity']
dont work for me.
What would be the correct way to get this output?
